TFA not only ruined the first instalment of the new trilogy by being shitty rehash, but it also made sure the second instalment will be a rehash at least to some degree. I do not think I will even go see Episode VIII. Even if I put the rehash aside, the characters made in TFA are quite boring and unlike-able. There is simply nothing for me to look forward to in new trilogy.
So essentially regardless of merit you’re going to trash the rest of the ST because you didn’t like TFA? Sounds fairly reasonable in 2017.
I did not particularly like any of the characters in TFA. I do not think they will all just disappear in the sequel.
